产品概述
The LM3280 is a multi-functional Power Management Unit, optimized for low-power handheld
applications such as Cellular Phones.The LM3280 incorporates three low-dropout LDO voltage regulators and one step down PWM
DC-DC converter with an internal Bypass FET. The step down converter's output voltage can be set
using an analog input (VCON) for optimizing efficiency of the RF PA at
various power levels. The LDO operates a nominal output voltage of 2.85V and maximum load current
capability of 20mA for a reference voltage required by linear RF power amplifiers. The LM3280
additionally features a separate enable pin for each output.The LM3280 is available in a 16-pin lead free DSBGA package.
